Abstract

Four new species of Trigonalyidae are described and illustrated from Qinling Mts (Shaanxi, NW China): Bareogonalos xibeidai Tan & van Achterberg, sp. n., Jezonogonalos mandibularis sp. n., J. shaanxiensis sp. n., and Taeniogonalos paraclypeata sp. n. Orthogonalys hirasana Teranishi, 1929, is re-instated and reported from China. The female of Taeniogonalos alticola (Tsuneki, 1991) is described for the first time. In total, 18 species are known from Shaanxi province, 20 species for NW China, and eight described species are newly recorded for Shaanxi: Jezonogonalos luteata Chen et al., 2014, Orthogonalys hirasana Teranishi, 1929, O. elongata Teranishi, 1929, Pseudogonalos hahnii (Spinola, 1840), Taeniogonalos alticola (Tsuneki, 1991), T. formosana (Bischoff, 1913), T. taihorina (Bischoff, 1914), and Teranishia glabrata Chen et al., 2014. Poecilogonalos maga Teranishi, 1929, syn. n. and Taiwanogonalos claripennis Tsuneki, 1991, syn. n. are new synonyms of Taeniogonalos taihorina (Bischoff, 1914) and Taiwanogonalos alishana Tsuneki, 1991, syn. n. of Taeniogonalos alticola (Tsuneki, 1991). Revised keys to species of the genera Bareogonalos, Jezonogonalos, and Orthogonalys are included.

Highlights

Trigonalyidae (Hymenoptera) is a worldwide small family in its own superfamily Trigonalyiodea, with 115 recognized species (Carmean and Kimsey 1998; Smith and Stocks 2005; Santos et al 2012; Smith and Tripotin 2012; Smith et al 2012, 2015; Chen et al 2014; Yamane 2014)
Trigonalyidae are fairly common at 1300-1500 m altitude in the Qinling Mts of Shaanxi (NW China)
18 species from Shaanxi are recorded in this paper, which is 41% of the 44 spp. known from China
